This invention relates to a machine designed for use" in forming groundmeats such as Hamburger steak or the like into cakes.

Thepriinary 'objectof theinvention is to provide a machine of thischaracter which will operate to compress the material and form it intocakes, without the necessity of the operator handling the material.

Another object of the invention isto provide a machine of this typewhich will be portable, and one which may be readily and easilydisassembled to facilitate cleaning.

A still further object of the invention is the provision of means forseparating the material formed into a cake, from the material containedin the body portion, and simultaneously ejecting the cake of materialfrom the mold in which it has been formed.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combimovable lifterbeing shown in its elevated position, in dotted lines.

Figure 3 is a sectional View taken on line 33 of Figure 2.

Referring to the drawings in detail, the reference character 5designates the base or support of the device, and asshown includes anupstanding enlargement 6, formed with i a square opening to receive thelower squared end of the post 'Z. The upper end of the post 7 is reducedas at 8 and includes a fun ther reduced portion 9 which is square to-fit within a square opening of the, lower end 10 of the cylindricalcontainer.

A wing nut 11 and washer 12 are mounted on the upper reduced end of thepost 7, and

cttoihold the cylindrical container in its operative position.

y The end member 10 is in the formof a casting provided withan opening13 and a funnel-shaped portion 14 thereabove, which funnel shaped .portion directs the ,material beinggformed intocakes, to the opening 13.

2 The cylindrical container whichis indicated by the reference character15, has its lower end threaded to fit within the upper end of thefunnel-shaped portion 14, so that the, cylindrical container isremovably supported. .i i

The upper end of the cylindrical container 15is closed by means. of thethreaded cap 16 which is formed with a threadedopenin'g toreceivethethreaded shank 17 to which the follower 18 is connected, the upperendof the shank 17"being provided with a handle19 whereby the shankmaybe rotated to feed :the follower .thro ngh the cylindrical, containerand exertfapressure on the material jSupporteddirectly under thecylindrical container is a pivoted member 20 which is formed with anopening to be fitted over the reduced portionfi of the post 7 the member"20 restingon the shoulder at the base'of ther educed portion 8; Anopening 21 is formed in the member 20gthe opening being provided wi thinwardly extended flange '22 acting as'a rest for the pusher 23, whichis *of' a diameter to closely fit within the opening2'1. i 1

Extending downwardly from the pusher 23, 1s "an arm 24: that is providedwith an elongated opening 25 to receive the laterally extended pin 26 ofthe bell crank lever '27 whichis pivotally supported at 28, and "mountedon the depending bracket 29 formed integral with the pivoted, member 20.

Pivotally connected with the bell crank lever is an armfidwhich isprovided with an upwardly andinwardly extended end portion 31 that isprovided with an elongatedfopening to accommodate the pin32, so that thearmflO m'ay sl de, for purposes to be hereinafter more fully described.i

flis clearly shown by Figure 3 of the drawin'gs, the inwardly extendedend 31 of the V as arm 30, engages one end of the lower end portion ofthe cylindrical container, the

edge being slightly curved-so that movement member and affords meanswhereby the member 20 may be'swung from a position directly under theend member '10, to a positionzlaterally thereof-to permit the cakeformed by e the devie,l t removed there 'from Q In. the use. of thedevice, the ground meat 7 I 520 ,vto be pressed into cakes, is placed inthe ing a funnel-shaped base formed with alateral extension, mountedonthe base, a swinging receiver under the base of the container,

'said lateral extension having a curved edge,

Said receiver having an opening to receive material from-the container,a pusher operating 1n the openlng, an arm shdablyinoun ed on the'receiver and contacting with the curved edge of the lateral extensionto move the arm laterally whentli'ereceiveris swung in a horizontalplane, and means for trans mitting movement of the arm to the pusher toforce material from the opening.
